Safety & Hazards

Species in this genus contain hydroxyanthracene derivatives which have a stimulant laxative effect upon the body, and many species are used traditionally as laxatives. In small doses, and for short periods, these can be safe and effective, but used over long periods they can weaken the body's natural ability to defecate and can have a range of long-lasting negative effects upon the body, including anaemia, malabsorption, haematuria and weight loss. Large single doses can cause severe purging.

Cultivation Details

HabitDeciduous Shrub
Growth—

Succeeds in any reasonably good soil[1]. Requires a well-drained soil in a sunny position[2]. The species in this genus are notably resistant to honey fungus[2]. This species is dioecious[3] - both male and female forms will need to be grown if fruit and seed are required.

Propagation

Seed - best sown in the autumn in a cold frame. Stored seed will require 1 - 2 months cold stratification and should be sown as early in the year as possible in a cold frame or outdoor seedbed. Germination is usually good, at least 80% by late spring. Prick out the seedlings into individual pots when they are large enough to handle, and grow them on in the greenhouse or cold frame for their first winter. Plant them out in late spring or early summer of the following year. Cuttings of half-ripe wood, mid summer in a frame. Cuttings of mature wood of the current year's growth, autumn in a frame. Layering in early spring. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-21. <temperate.theferns.info/plant/Rhamnus+utilis>
